Food prices in Nunavut

Food prices in Nunavut (in Arctic Canada) are legendarily high, because pretty much everything that’s not “country food” (traditional local food such as seal, berries, etc.) is imported by air from the south.

Here’s a blog post that includes a flyer from a local supermarket, showing what sale prices are like in Baker Lake (Qamani'tuaq, ᖃᒪᓂᑦᑐᐊᖅ).

Those of you from other parts of Canada may wish to compare the prices (especially for the small variety of fresh produce) with what you pay at your local supermarket; those of you from other places will have to do currency conversion (and possibly purchasing-power-parity adjustments).

V.90 modem handshake diagram

The Sound of the Dialup: an Example Handshake by Oona Räisänen (2500×1301px JPEG, cc-by-sa 3.0)

via dotaturls

A fascinating, annotated image of what a modem handshake (V.90, apparently) looks like when split up into frequences (is that called a spectrogram?), and what the individual bits mean.

A pity that my modem days were so long ago that I don’t really recall what the handshake sounded like; it would have been even more fun to correlate the sound I heard with the visual description in that image.



Current Mood: geeky
